The following Pie-Charts show the percentage of different categories (A, B, C, D, E and F) of employees in a company in the year 2019 and 2020. The total number of employees was 4000 in 2019 and 5000 in 2020.
What was the percentage increase of category-E employees in 2020 as compared to that in 2019 ?
25%
Given:
Total number of employees in 2019 = 4000
Total number of employees in 2020 = 5000
Calculation:
For category A,
Total number employee of category A in 2019 = 20 × 4000/100 = 800
Total number employee of category A in 2020 = 22 × 5000/100 = 1100
For category B,
Total number employee of category B in 2019 = 6 × 4000/100 = 240
Total number employee of category B in 2020 = 10 × 5000/100 = 500
For category C,
Total number employee of category C in 2019 = 10 × 4000/100 = 400
Total number employee of category C in 2020 = 11 × 5000/100 = 550
For category D,
Total number employee of category D in 2019 = 15 × 4000/100 = 600
Total number employee of category D in 2020 = 9 × 5000/100 = 450
For category E,
Total number employee of category E in 2019 = 27 × 4000/100 = 1080
Total number employee of category E in 2020 = 27 × 5000/100 = 1350
For category F,
Total number employee of category F in 2019 = 22 × 4000/100 = 880
Total number employee of category F in 2020 = 21 × 5000/100 = 1050
Required Percentage = [(1350 - 1080)/1080] × 100 = 25%
∴ The correct answer is 25%
